Description

Die Erfindung bezieht sich auf einen Fehlerstromschutzschalter, auf dessen Sockel Summenstromwandler, Auslöser und Schaltschloß angeordnet sind und dessen Sockel von einer Schaltwalze betätigte Schaltkontakte auf-. nimmt. Fehlerstromschutzschalter dieser Art sind bekannt (FR-A-13 47 629).The invention relates to a residual current circuit breaker on whose base summation current transformers, triggers and switch lock are arranged and the base of switching contacts actuated by a switching drum. takes. Residual current circuit breakers of this type are known (FR-A-13 47 629).

Fehlerstromschutzschalter sind im Laufe der Jahre zunehmend gedrungener und kleiner gebaut worden, um sie in Verteilungen raumsparend unterzubringen. Diesen Bestrebungen steht unter anderem entgegen, daß unvermeidliche Toleranzen bei Kunststoffgehäusen aufwendige Vorkehrungen erfordern, um zwischen dem Handbedienungshebel und dem Gehäuse größere Spalte als es die Sicherheitsvorschriften erlauben, zu vermeiden.Residual current circuit breakers have become increasingly compact and smaller over the years in order to accommodate them in distributors to save space. These efforts stand in the way, inter alia, that inevitable tolerances in plastic housings require elaborate measures to avoid gaps between the hand control lever and the housing that are larger than the safety regulations allow.

Der Erfindung liegt die Aufgabe zugrunde, einen gedrungenen Fehlerstromschutzschalter niedrig aufzubauen und dennoch Toleranzen auszugleichen.The invention has for its object to build a compact residual current circuit breaker low and still compensate for tolerances.

Die Lösung der geschilderten Aufgabe wird durch einen Schalter mit den Merkmalen nach Kennzeichen des Anspruchs 1 erzielt. Durch die Anordnung der Löschbleche unter einer Anschlußklemme und durch Ausbildung als Baugruppe mit dem Festkontakt wird die Fertigung erleichtert und Platz gespart. Dabei ist es im Prinzip bekannt, Schaltkontaktstücke jeweils an einem kippbeweglich abgestützten Hebel anzuordnen und durch eine den Kontakthebel beaufschlagende Feder den Kontaktdruck zu erzeugen und sie zugleich als Schaltfeder zu verwenden. Bei einem solchen bekannten Fehlerstromschutzschalter (US-A-34 40 579) ist der kippbewegliche Hebel zweiteilig ausgebildet, so daß eine Bewegung nach Art eines Kniegelenks zustandekommt. Beim bekannten Fehlerstromschutzschalter sind die Löschbleche in einem über die ganze Gehäusehöhe reichenden Schaltraum untergebracht. Anschlußklemmen sind diesem Schaltraum in der Erstreckungsebene noch seitlich vorgelagert. Ein solcher Fehlerstromschutzschalter ist verhältnismäßig raumaufwendig und es wird dabei kein Beitrag zur Vermeidung der Toleranzen bei gedrungen aufgebauten Fehlerstromschutzschaltern gegeben, wie es gerade Ziel der vorliegenden Erfindung ist.The solution to the problem is achieved by a switch with the features according to the characterizing part of claim 1. The arrangement of the quenching plates under a connection terminal and by design as an assembly with the fixed contact simplifies production and saves space. In principle, it is known to arrange switching contact pieces on a lever supported in a tiltable manner and to generate the contact pressure by means of a spring acting on the contact lever and at the same time to use it as a switching spring. In such a known residual current circuit breaker (US-A-34 40 579), the tiltable lever is formed in two parts, so that a movement occurs in the manner of a knee joint. In the known residual current circuit breaker, the quenching plates are accommodated in a switch room that extends over the entire height of the housing. Terminals are laterally upstream of this control room on the extension level. Such a residual current circuit breaker is relatively space-consuming and there is no contribution to avoiding the tolerances in compact residual current circuit breakers, as is the aim of the present invention.

Die Löschbleche können unter der Anschlußklemme in etwa parallel zur Basis des Fehlerstromschutzschalters angeordnet werden, wodurch ausgeblasene heiße Gase weder den Bereich der Anschlußklemme noch der Tragschiene unter der Basis des Fehlerstromschutzschalters gefährden. Beim bekannten Schalter (US-A-34 40 579) sind die Anschlußklemmen hinter besonders sicher isolierenden dicken Wänden unterzubringen.The quenching plates can be arranged under the connection terminal approximately parallel to the base of the residual current circuit breaker, so that blown out hot gases do not endanger the area of the connection terminal or the mounting rail under the base of the residual current circuit breaker. In the known switch (US-A-34 40 579), the connection terminals are to be accommodated behind thick walls which are particularly safe to insulate.

Dadurch, daß die Schaltkontaktstücke jeweils an einem kippbeweglich abgestützten Hebel angeordnet sind, läßt sich eine Untersetzung des zum Öffnen der Kontakte erforderlichen Drehmoments hinsichtlich der Schaltwalze erreichen. Dadurch kann das Schaltschloß schwächer und kleiner gehalten werden und dadurch zur kompakten Bauweise beitragen.Characterized in that the switching contact pieces are each arranged on a lever supported in a tiltable manner, a reduction in the torque required to open the contacts with respect to the switching drum can be achieved. This allows the key switch to be kept weaker and smaller, thereby contributing to the compact design.

Ein weiterer wesentlicher Vorteil des Fehlerstromschutzschalters nach der Erfindung liegt darin, daß ein weiter Durchgriff im Sockel des Fehlerstromschutzschalters das Montieren erleichtert und durch ein besonders ausgebildetes Dichtungsstück sicher verschlossen wird. Dieses Dichtungsstück übernimmt gleichzeitig die Funktion, Leitungen geordnet festzulegen. Es lassen sich kurze Leitungswege erzielen.Another significant advantage of the residual current circuit breaker according to the invention is that a further penetration in the base of the residual current circuit breaker facilitates assembly and is securely closed by a specially designed sealing piece. At the same time, this sealing piece takes on the function of determining lines in an orderly manner. Short cable routes can be achieved.

Durch eine Zentriernase an der Abdeckhaube des Schaltergehäuses, die zwischen die Lagerplatinen des Schaltschlosses eingreift, wird sichergestellt, daß zwischen Handbetätigungsgriff und Kunststoffgehäuse auch bei üblichen Toleranzen nur kleine zulässige Spalte auftreten können. Die Abdeckhaube des Gehäuses kann insbesondere eine Mulde mit Durchgriff für das Handbetätigungsorgan des Schaltschlosses aufweisen, um es gegen seitliche Einwirkungen zu schützen. Dabei kann die Prüftaste flächig und quadratisch ausgebildet werden, was die Handhabung erleichtert.A centering lug on the cover of the switch housing, which engages between the bearing plates of the switch lock, ensures that only small permissible gaps can occur between the manual operating handle and the plastic housing, even with usual tolerances. The cover of the housing can in particular have a trough with a passage for the manual actuating element of the switch lock in order to protect it against lateral influences. The test button can be flat and square, which makes handling easier.

Der Fehlerstromschutzschalter soll anhand eines in der Zeichnung grob schematisch wiedergegebenen Ausführungsbeispiels näher erläutert werden:

  • In Fig. 1 ist der Fehlerstromschutzschalter nach einem Schnitt senkrecht zur Schaltwalze wiedergegeben.
  • In Fig. 2 ist der Fehlerstromschutzschalter von der Seite gesehen, teilweise aufgebrochen, wiedergegeben.
  • In Fig. 3 ist die Aufsicht dargestellt.
  • In Fig. 4 ist der Fehlerstromschutzschalter von der Stirnseite beim Handbetätigungsorgan veranschaulicht.
  • In den Figuren 5 bis 7 ist ein Teil des zweiteiligen Dichtungsstücks des Fehlerstromschutzschalters in größerem Maßstab in Ansicht in Richtung der Schaltwalze, von oben, bzw. von der Seite dargestellt.
The residual current circuit breaker is to be explained in more detail using an exemplary embodiment shown roughly schematically in the drawing:
  • In Fig. 1 the residual current circuit breaker is shown after a cut perpendicular to the shift drum.
  • In Fig. 2 the residual current circuit breaker is seen from the side, partially broken open, shown.
  • The supervision is shown in FIG. 3.
  • In Fig. 4, the residual current circuit breaker is illustrated from the front in the manual actuator.
  • In FIGS. 5 to 7, part of the two-part sealing piece of the residual current circuit breaker is shown on a larger scale in the direction of the shift drum, from above or from the side.

Der Fehlerstromschutzschalter nach Fig. 1 weist bewegliche Schaltkontaktstücke 1 auf, die jeweils an einem Kontakthebel 2 angeordnet sind. Der Kontakthebel 2 stützt sich kippbe-' weglich am Sockel an der Stützwand 4 ab. Auf seiner einen Seite ist der Köntakthetiel 2 von einer Feder 5 beaufschlagt, die sich als Druckfeder am Hebel abstützt. Jenseits des Abstütxpunktes ist das Schaltkontaktstück 1 angeordnet. Zu diesem ist gegenüberliegend das ortsfeste Kontaktstück 6 an einer Laufschiene 7 angeordnet. Die Laufschiene ist auf ihrer einen Seite mit einer Anschlußklemme 8 elektrisch verbunden. Auf ihrer anderen Seite geht die Laufschiene 7 in ein außenliegendes Löschblech bzw. eines Leitbleches 9 eines Löschblechstapels 10 über. Anschlußklemme 8, Laufschiene 7 und Löschblechstapel 10 lassen sich als Baugruppe ausf.ühren.1 has movable switching contact pieces 1, which are each arranged on a contact lever 2. The contact lever 2 based kippbe- 'movably on the base on the support wall 4 from. On one side, the top contact 2 is acted upon by a spring 5, which is supported on the lever as a compression spring. Beyond the support point, the switching contact piece 1 is arranged. The stationary contact piece 6 is arranged on a running rail 7 opposite this. The running rail is electrically connected on one side to a connecting terminal 8. On its other side, the running rail 7 goes into an external one Quenching plate or a baffle 9 of a stack of quenching plates 10 over. Terminal 8, running rail 7 and stack of fire-extinguishing sheets 10 can be designed as an assembly.

Durch die zur Seite verlaufenden Löschbleche des Löschblechstapels 10 können aus der Ausblasöffnung 11 austretende Schaltgase weder die Anschlußklemme 8 noch eine an der Basis 12 befindliche Tragschiene gefährden.Due to the extinguishing plates of the stack of extinguishing plates 10 running to the side, switching gases escaping from the blow-out opening 11 cannot endanger the connecting terminal 8 or a mounting rail located on the base 12.

Der dargestellte Kontakthebel 2 und weitere Kontakthebel für weitere Pole werden von der Schaltwalze 13, deren gedachte Achse mit 14 bezeichnet ist, durch Mitnehmer 15 betätigt. Das zur Kontaktöffnung erforderliche Drehmoment ist durch die Abstützung des Kontakthebels 2 hinsichtlich der Schaltwalze 13 untersetzt.The contact lever 2 shown and further contact levers for further poles are actuated by the shift drum 13, the imaginary axis of which is designated 14, by drivers 15. The torque required for the contact opening is reduced by the support of the contact lever 2 with respect to the shift drum 13.

Ein Durchgriff zum Sockel 3 ist durch ein zweiteiliges Dichtungsstück verschlossen, dessen eines Teil 17 eine im Profil U-förmige Aufnahme 18 bildet. Neben dieser Aufnahme 18 verbleibt ein kleinerer Durchgriff, der durch ein weiteres Teil 20 überdeckt ist. Das Teil 20 bildet eine Klemmschulter 21 zum ersten Teil 17 des Dichtungsstückes 16. Zwischen den Klemmschultern 21 der Teile 17 und 20 können Leitungen 22 geordnet festgeklemmt werden. In der Aufnahme 18 läßt sich eine Leitungsverbindung zwischen den Leitungen 22 und 23 unterbringen. Die Leitungen können in der Aufnahme 18 festgeklemmt werden. Durch einen solchen Aufbau erzielt man in Verbindung mit der geschilderten Anordnung der Bauteile kurze Leitungswege und eine gute Abdichtung der Schaltkontakte zum Wandlerraum.A passage to the base 3 is closed by a two-part sealing piece, one part 17 of which forms a U-shaped receptacle 18 in profile. In addition to this receptacle 18, there remains a smaller passage which is covered by a further part 20. The part 20 forms a clamping shoulder 21 to the first part 17 of the sealing piece 16. Between the clamping shoulders 21 of the parts 17 and 20, lines 22 can be clamped in an orderly manner. A line connection between the lines 22 and 23 can be accommodated in the receptacle 18. The lines can be clamped in the receptacle 18. Such a construction, in conjunction with the arrangement of the components described, achieves short conduction paths and a good seal of the switching contacts to the converter space.

Die Leitung 23 ist durch den Summenstromwandler 24 hindurchgeführt und mit der anderen Anschlußklemme 8a elektrisch verbunden.The line 23 is passed through the summation current transformer 24 and electrically connected to the other connection terminal 8a.

Unter der Abdeckhaube 25 des Schaltgehäuses sind senkrecht zur Zeichenebene außer dem Summenstromwandler 24 der Auslöser und das Schaltschloß sowie Teile der Prüfvorrichtung angeordnet. Für weitere Bauteile bleibt unter der Anschlußklemme 8a sowie den benachbarten Anschlußklemmen Raum. An der Basis 12 ist eine übliche Schnapphalterung zum Aufreihen auf Tragschienen ausgebildet.Under the cover 25 of the switch housing, in addition to the summation current transformer 24, the trigger and the switching lock and parts of the test device are arranged perpendicular to the plane of the drawing. There is space for further components under the connection terminal 8a and the adjacent connection terminals. At the base 12, a customary snap-in bracket is arranged for lining up on mounting rails.

Wie aus Figur 2 im einzelnen zu ersehen ist, bildet die Abdeckhaube 25 eine Zentriernase 26, die zwischen die Lagerplatine 27 des Schaltschlosses 28 eingreift. Das Schaltschloß 28 ist lediglich an seinem Fuß befestigt. Das Schaltschloß 28 findet seine Endlage durch Führung an der Zentriernase 26. Dadurch ist sichergestellt, daß zwischen Handbetätigungsorgan 29 und der Abdeckhaube des Schaltergehäuses trotz großer Toleranz bei Kunststoffteilen nur kleine definierte Spalte zulässiger Größenordnung entstehen.As can be seen in detail from FIG. 2, the cover 25 forms a centering lug 26 which engages between the bearing plate 27 of the switching lock 28. The switch lock 28 is only attached to its foot. The switch lock 28 finds its end position by guiding the centering lug 26. This ensures that, despite the large tolerance for plastic parts, only small, defined gaps of permissible size are created between the manual actuating member 29 and the cover of the switch housing.

Die Abdeckhaube 25 bildet im Ausführungsbeispiel eine Mulde 36 mit dem Durchgriff für das Handbetätigungsorgan 29.In the exemplary embodiment, the cover hood 25 forms a trough 36 with the passage for the manual actuating element 29.

Die Prüftaste 30 kann, wie es auch aus Figur 3 zu ersehen ist, flächig und quadratisch ausgebildet werden. Die Anschlußklemmen 8 und 8a sind zum Anschließen des Mittelpunktleiters und von drei Phasenleitern bestimmt.As can also be seen from FIG. 3, the test button 30 can be made flat and square. The terminals 8 and 8a are intended for connecting the center conductor and three phase conductors.

Das zweite Teil des zweiteiligen Dichtungsstückes 16, das Teil 20, ist in Figur 5 in der Ansicht entsprechend Figur 1 vergrößert dargestellt. Auch dieses Teil kann mittels Rastfüßen 31 ebenso wie das erste Teil 17 des Dichtungsstückes 16, nach dem Einsetzen im Sockel verrasten. Die Rastfüße 31 sind aus Figure 7 zu ersehen.The second part of the two-part sealing piece 16, the part 20, is shown enlarged in FIG. 5 in the view corresponding to FIG. 1. This part, too, can be locked by means of locking feet 31, like the first part 17 of the sealing piece 16, after insertion in the base. The locking feet 31 can be seen in Figure 7.
